1. Bomb down to the purple egg plants. Then bomb to the right to the green kiwis.
2. Bomb down to the blue fruits. Then to the right to the red ones. Then up to the yellow ones. Hint: use color switches to remove fruits whenever possible.
3. Destroy one wooden block so that you have access to the lower right chamber.
Now comes the tricky part. Go back to the yellow fruits and take the remaining bomb.
Try to get through the small hole in the wooden blocks without losing your bomb. Then use the bomb to open a passage to the cyan fruit blocks.
